A thin button with a limiting block 5 is characterized in that a reset mechanism comprises two symmetrically arranged transmission parts 7 and an elastic component bridged between the transmission parts 7, wherein the transmission parts 7 are stressed and abut against the limiting block 5 when swinging from an idle station to a stressed station, so that the elastic component stretches and accumulates pre-tightening force for driving a transmission rod 9 to return to the idle station.

When the circuit board is installed, firstly, the circuit board 4 is fixedly connected to the middle of the bottom wall of the installation cavity 2, and the corresponding rotating shafts 12 among the transmission rods 9 are connected through the sleeve 6; then, the transmission rods 9 are installed at two sides of the installation cavity 2 and are inserted into the corresponding clamping openings 11 through the swing rods 10; then, the pressing plate 14 is arranged above the triggering part of the circuit board 4, and the elastic component is connected to the corresponding transmission rod 9; then, two ends of the spring 13 are respectively and fixedly connected to the end edge of the pressing plate 14 and the corresponding transmission rod 9; finally, the button body 3 is inserted into the mounting cavity 2 and fixedly connected with the top surface of the pressure plate 14.

After the circuit board is installed in place, the spring 13 drives the transmission rod 9 to approach the pressing plate 14 by using the elasticity of the spring 13, so that the transmission rod 9 swings upwards to the upper limit station and pulls the pressing plate 14 to move upwards through the spring 13, and at the moment, the pressing plate 14 is separated from the trigger part, and the circuit board 4 is ensured to be maintained in an idle state.
